Dear community,
I have an input file with prices (base price and hourly rate) for a list of contracts. Whenever a price has changed, the list contains a new entry (date and new price) for the contract.
I am trying to find the time of the latest two price adaptations (valid from) as an output in my target file.
How do I parse the input file to find the latest date at which price changes have been made?
The input file contains about 100.000 contract entries and 500.000 rows.
Thanks for any help regarding this 🙂
